The X-Ray Luminosity Function of Nearby Rich and Poor Clusters of Galaxies:A Cosmological Probe
(American Astronomical Society, 1999)
In this Letter, we present a new determination of the local (z · 0.09) X-ray luminosity function (XLF) using a large, statistical sample of 294 Abell clusters and the ROSAT All-Sky Survey. Despite the optical selection of ...
A catalog of Nearby Poor Clusters of Galaxies
(American Astronomical Society, 1999)
A catalog of 732 optically selected, nearby poor clusters of galaxies covering the entire sky north of [3¡ declination is presented. The poor clusters, called WBL clusters, were identified as concentrations of
three or ...
Massive Cooling Flow Clusters Inhabit Crowded Environments
(American Astronomical Society, 1999)
With the availability of large-scale redshift survey data, it is now becoming possible to explore correlations between large-scale structure and the properties and morphologies of galaxy clusters. We investigate the spatial ...
Weak Gravitational Lensing and Cluster Mass Estimates
(American Astronomical Society, 1999)
Hierarchical theories of structure formation predict that clusters of galaxies should be embedded in a weblike structure, with filaments emanating from them to large distances. The amount of mass contained within such ...
Center of mass and relative motion in time dependent density functional theory
(American Physical Society, 1995)
It is shown that the theorem asserting separability of the center of mass motion for a system of interacting particles in a harmonic external potential is satisfied in the time dependent density functional theory, provided ...
Mass and Metallicity of Five X-Ray-bright Galaxy Groups
(American Astronomical Society, 1999)
We present ASCA X-ray observations of a sample of Ðve groups selected from a cross-correlation of the ROSAT All-Sky Survey with the White et al. optical catalog of groups. These X-rayÈbright groups significantly increase ...
X-ray scattering from rotational disorder in epitaxial films: An unconventional mosaic crystal
(American Physical Society, 1995)
Motivated by x-ray-scattering measurements performed on ErAs(001)/GaAs(001) and In0.7Ga0.3P(001)/GaAs(001), we present a model that explains the origin of a narrow peak and diffuse scattering, which are frequently observed ...
Mashhoon replies
(American Physical Society, 1992)
B. Mashhoon discusses comments made by J. Anandan on the results on the coupling of intrinsic spin to the angular velocity in a neutron interferometry.(AIP)
Theory of photon bands in three-dimensional periodic dielectric structures
(American Physical Society, 1990)
Recent experiments have found the existence of ''photon bands'' in periodic dielectric structures analogous to the electron bands in the solid. Using a plane-waves method, we study in the scalar-wave approximation the ...
Erratum: Theory of photon bands in three-dimensional periodic dielectric structures
(American Physical Society, 1990)
Erratum correction in reference to Theory of Photon Bands in Three-Dimensional Periodic Dielectric Structures [Phys Rev. Lett. 64 1239 (1990)].

Gravitomagnetism and the Clock Effect
(arXiv, 1999)
The main theoretical aspects of gravitomagnetism are reviewed. It is shown that the gravitomagnetic precession of a gyroscope is intimately connected with the special temporal structure around a rotating mass that is ...
Multilayer structure of nitrogen adsorbed on graphite
(American Physical Society, 1989)
Elastic neutron diffraction has been used to study the structure and layering of nitrogen films adsorbed on the (002) surfaces of an exfoliated graphite substrate. The neutron-diffraction pattern of the fully compressed ...
On the Energy of Rotating Gravitational Waves
(arXiv, 1996)
A class of solutions of the gravitational field equations describing vacuum spacetimes outside rotating cylindrical sources is presented. A subclass of these solutions corresponds to the exterior gravitational fields of ...
Melting mechanism in monolayers of flexible rod-shaped molecules
(American Physical Society, 1992)
The melting of butane and hexane monolayers adsorbed on a graphite basal-plane surface has been studied by molecular-dynamics simulations and experimentally by neutron diffraction. The simulation results are qualitatively ...
Synchrotron x-ray-diffraction study of the structure and growth of Xe films adsorbed on the Ag(111) surface
(American Physical Society, 1999)
Synchrotron x-ray scattering has been used to investigate the structure and growth of perhaps the simplest of all films: xenon physisorbed on the Ag(111) surface. High-resolution x-ray scans of the in-plane structure and ...
Evolutionary dynamics while trapped in resonance: a Keplerian binary system perturbed by gravitational radiation
(American Institute of Physics, 1997)
The method of averaging is used to investigate the phenomenon of capture into resonance for a model that describes a Keplerian binary system influenced by radiation damping and external normally incident periodic gravitational ...
On Measuring Gravitomagnetism via Spaceborne Clocks: A Gravitomagnetic Clock Effect
(arXiv, 1998)
The difference in the proper azimuthal periods of revolution of two standard clocks in direct and retrograde orbits about a central rotating mass is proportional to J/Mc^2, where J and M are, respectively, the proper angular ...
Rotating cylindrical systems and gravitomagnetism
(arXiv, 1998)
We discuss gravitomagnetism in connection with rotating cylindrical systems. In particular, the gravitomagnetic clock effect is investigated for the exterior vacuum field of an infinite rotating cylinder. The dependence ...
On detecting the gravitomagnetic field of the earth by means of orbiting clocks
(arXiv, 1998)
Based on the recent finding that the difference in proper time of two clocks in prograde and retrograde equatorial orbits about the Earth is of the order 10^{-7}s per revolution, the possibility of detecting the terrestrial ...
